SHOCKING! Two Japanese boxers die of brain injuries at same Tokyo event

The US Senate Intelligence Committee said on Friday they were investigating incidents of a mysterious "directed" radio energy on US diplomats, known as the "Havana syndrome".

The investigation is being carried out after media reports of potentially brain-damaging ailments in Cuba.&nbsp;

The US intel agencies have intensely investigated a series of health incidents, deemed “directed-energy attacks,” which have injured American officers in Cuba, China, Russia, and elsewhere.&nbsp;

Havana syndrome is a set of medical signs and symptoms reported by the United States and Canadian embassy staff in Cuba dating back to late 2016 as well as subsequently in some other countries, including the United States.

US diplomats were hit by the mysterious, debilitating illness consistent with Traumatic Brain Injury.

Complaints include ear-popping, vertigo, pounding headaches and nausea, sometimes accompanied by an unidentified “piercing directional noise.”

Over the past two years, two such incidents have reportedly occurred in the US&nbsp;including one close to the White House.

The majority of the incidents have involved officials stationed in other countries.

According to a report by The New York Times, three CIA officers had reported serious symptoms since December, following overseas assignments, requiring outpatient treatment at the Walter Reed military hospital in Washington. One episode was within the past two weeks.

In many of the cases, the officers felt so sick, so suddenly, that they required emergency medical evacuation, two people familiar with the matter said. The recent incidents have taken place on three continents, according to one source. &nbsp;

The US Department of Defence has been working on a wearable sensor that would detect invisible radio frequencies to stop the ‘Havana syndrome’ energy attack.

Havana syndrome brain injury: 130 US spies, diplomats, officials hit by mysterious illness

Researchers have revealed how the brain encodes time and place into memories in the latest study conducted by the University of Texas.

The findings published in PNAS and Science could eventually provide the basis for new treatments to combat memory loss from conditions such as traumatic brain injury or Alzheimer's disease.

About 10 years prior, a gathering of neurons known as "time cells" was found in rodents. These cells seem to assume an extraordinary part in chronicle when occasions occur, permitting the cerebrum to accurately check the request for what occurs in a wordy memory.&nbsp;

Situated in the cerebrum's hippocampus, these phones show a trademark movement design while the creatures are encoding and reviewing occasions, clarifies Bradley Lega, a partner teacher of a neurological medical procedure at University of Texas Southwestern Medical School (UTSW) and senior creator of the PNAS study.&nbsp;

By terminating in a reproducible arrangement, they permit the cerebrum to coordinate when occasions occur, Lega says. The circumstance of their terminating is constrained by 5 Hz cerebrum waves, called theta motions, in a cycle known as precession.&nbsp;

Lega examined whether people likewise have time cells by utilizing a memory task that sets solid expectations for time-related data. Lega and his associates enlisted volunteers from the Epilepsy Monitoring Unit at UT Southwestern's Peter O'Donnell Jr. Mind Institute, where epilepsy patients remain for a few days before the medical procedure to eliminate harmed portions of their cerebrums that flash seizures. Cathodes embedded in these patients' cerebrums assist their specialists with recognizing the seizure foci and furthermore give important data on the mind's internal functions, Lega says.&nbsp;

While recording electrical movement from the hippocampus in 27 volunteers' cerebrums, what the group discovered was energizing: Not just did they recognize a powerful populace of time cells, however, the terminating of these phones anticipated how well people had the option to connect words together as expected (a marvel called fleeting bunching). At last, these cells seem to show stage precession in people, as anticipated.&nbsp;

"For quite a long time researchers have suggested that time cells resemble the magic that binds recollections of occasions in our lives," as indicated by Lega. "This finding explicitly underpins that thought in an exquisite manner."&nbsp;

In the second examination in Science, Brad Pfeiffer, associate educator of neuroscience, driven a group researching place cells—a populace of hippocampal cells in the two creatures and people that records where occasions happen.&nbsp;

Analysts have since quite a while ago referred to that as creatures travel a way they've been on previously, neurons encoding various areas along the way will fire in succession much like time cells fire in the request for worldly occasions, Pfeiffer clarifies. Likewise, while rodents are effectively investigating a climate, place cells are additionally coordinated into "small scale arrangements" that speak to a virtual compass of areas in front of the rodent. These radar-like ranges happen about 8-10 times each second and are believed to be a mind system for foreseeing promptly impending occasions or results.&nbsp;

Before this examination, it was realized that when rodents quit running, place cells would frequently reactivate in long groupings that seemed to replay the rodent's related knowledge in the opposite. While these "converse replay" occasions were known to be significant for memory development, it was hazy how the hippocampus had the option to create such successions. For sure, impressive work had shown that experience ought to fortify forward, "look forward" successions, however, debilitate switch replay occasions.&nbsp;

To decide how these retrogressive and forward recollections cooperate, Pfeiffer and his associates set anodes in the hippocampi of rodents, at that point permitted them to investigate two better places: a square field and a long, straight track. To urge them to travel through these spaces, they put wells with chocolate milk at different spots. They at that point broke down the creatures' place cell action to perceive how it compared to their areas.&nbsp;

Specific neurons terminated as the rodents meandered through these spaces, encoding data on spot. These equivalent neurons terminated in a similar arrangement as the rodents remembered their ways, and occasionally terminated backward as they finished various legs of their excursions. In any case, investigating the information, the specialists discovered something new: As the rodents traveled through these spaces, their neurons showed forward, prescient smaller than normal successions, yet in addition in reverse, review scaled-down arrangements. The forward and in reverse groupings rotated with one another, each taking a couple of dozen milliseconds to finish.&nbsp;

"While these creatures were pushing ahead, their cerebrums were continually exchanging between expecting what might occur straightaway and reviewing what simply occurred, all inside portion of-a-second time spans," Pfeiffer says.&nbsp;

Pfeiffer and his group are at present examining what inputs these cells are accepting from different pieces of the cerebrum that cause them to act in these forward or turn around designs.&nbsp;

In principle, he says, it very well may be conceivable to capture this framework to help the mind review where an occasion occurred with greater constancy. Essentially, adds Lega, incitement strategies may in the end have the option to copy the exact designing of time cells to help individuals all the more precisely recollect fleeting successions of occasions.
